1 Claim.

This invention relates to looms for the weaving of textile fabrics and in such connection it has more particular reference to a shuttle guard attachment for guiding the shuttle of the loom back 5 into its path when deflected therefrom.

The invention has particular relation to looms of the Draper X-model types and also of the Stafiord and similar makes of looms. In the operation of such looms the shuttle which carries the bobbin across the warp threads in the weaving of the cloth is frequently deflected from its path, resulting in the shuttle being smashed or damaged.

It is the primary object of this invention to provide a shuttle guard attachment for the protection of the shuttles in looms of the above mentioned and similar types to prevent injury to the shuttle, said attachment engaging the point of the shuttle when the latter is deflected from its path from any cause and guiding it back into the shuttle race, of the loom.

Another object of the invention is to provide an attachment of the above described character which includes a shock-absorbing means to further prevent possible injury to the shuttle.

With the above objects in view, the invention will be clearly understood from a perusal of the following detailed description, taken in connection with the accompanying drawing and in said drawing:

Figure 1 is a plan view of the shuttle box mouth plate of a Draper X-model loom with the attachment embodying the invention fastened thereto.

Figure 2 is a cross-sectional view of Figure 1,

the view taken along the line 22 of Figure 1,

Figure 3 is a bottom view of the attachment removed from the shuttle box mouth plate,

Figure 4 is a perspective view of a portion of a loom of another type and illustrating a modification of the invention mounted thereon, and

Figure 5 is a plan view of the modified form of the attachment shown in Figure 4, the view being partly broken away.

Reference being had more in detail to the drawing, and wherein like parts will be designated by like reference characters, I denotes the shuttle box mouth plate of a Draper X-model loom to which the attachment embodying the invention is secured and having connection with the mouth plate on the battery side of the loom. This attachment consists of an elongated piece of metal 2 with a portion thereof disposed at substantially right angles to the body 2 and forming a tongue 3, more clearly shown in Figures 2 and 3. The

body 2 has spaced holes 4 for the insertion of screws 5 whereby the attachment may be secured to the shuttle box mouth plate as revealed in Figures 1 and 2. Welded or otherwise securely fastened to the tongue 3 of the attachment is another piece of metal 6, one end being directed outwardly as at 6-a. Embracing the portions 3, 6 and 6a is a strip of leather or similar material of toughpliable nature I, the ends thereof as at 7-11 being lapped over each other. In these ends 'l-a as well as the portions 3, 6 and 6-a of the 10 attachment are holes in alinement one with the other to receive a screw 8, whereby the leather covering is securely held in position.

In Figure 5 the attachment is shown modified to accommodate-types of looms diflerent in struc- 5 ture from the X model Draper type. In this form of the attachment the body 9 is made of steel of sufiicient thinness to provide resiliency. Integral with the body 9 is a tongue l0. Figure 4: shows this modified form of the attachment in 20 operative position on thebattery side or end of the reed cap II, the reed being indicated at l2. For this purpose the tongue has a hole for the reed cap bolt l3 for securing the attachment in I position, as will be apparent. The race plate for 25 the travel of the shuttle, the guard and the lay are indicated respectively at I4, l5 and Hi.

The body 9 of the modified form of the attachment is covered on each side by pieces of leather I1, the leather or similar material being secured 30 thereto by the rivets l8 passing through the body 9 and the covering.

As the shuttle travels along the race plate l4 and should it for any cause be deflected from its path, it is thrown into the attachment or guard 5 constituting the invention and the leather covering absorbs the shock to an extent sufiicient to prevent the shuttle from being injured or broken. The body 9 and the tongue 10 are made of steel thin enough to give with the shock of the shuttle 4 and assist in absorbing the same. This guard can be affixed to both ends of the reed cap, but is most efiective at the battery end, and can be applied thereto as explained by the reed cap bolt l3 and so adjusted as to clear the temple and 45 the cloth.

It is believed that the preceding description will be sufficient to those skilled in the art to which the invention relates. Both forms of the invention may be changed, altered and further modified 50' to an extent within the scope and meaning of the claim appended hereto without departing from the spirit of the invention. i

What is claimed as new is:

A shuttle guard attachment for looms, in com- 55 bination with the shuttle box mouth plate of the loom, said attachment comprising a metal plate having an elongated body and a tongue projecting from the body at substantially right angles thereto, said body having apertures for fastening the body of the plate to the shuttle box mouth plate of the loom, said tongue having a piece of metal secured thereto across the endof the tongue, one

end of said piece being curved outwardly from the tongue and a covering of resilient yieldable material embracing said curved piece of metal and said tongue, and means for holding the covering in position.
